What device is typically used to trace a logic path?

The device typically used to trace a logic path is a logic analyzer. A logic analyzer is specifically designed to capture and display multiple signals from a digital circuit, providing a visual representation of the logical states and transitions over time. This functionality allows technicians to determine if the logic paths are functioning as intended, facilitating the debugging and analysis of complex digital systems.

In contrast, while options like an oscilloscope can visualize waveforms and digital signals, it is not optimized for analyzing multiple logic states at once. Similarly, a digital multimeter is primarily used for measuring electrical values such as voltage, current, and resistance, and lacks the capability to analyze logic levels in a digital context. A logic pulsar, while it can generate signals and aid in testing, does not have the analytical capabilities of a logic analyzer for tracing and observing logic paths in detail.
